PSX series scrap steel crushing production line

Uses and characteristics

◇ Use

The scrap steel crushing production line is today's advanced scrap steel processing equipment. It is mainly used to process waste car bodies, tinplates, household appliances, bicycles, empty cans, etc., to make them into top-quality steel materials. Continuously pulverize, remove the coating film, increase the specific gravity, prevent explosion when the electric furnace is put into the electric furnace, and increase the dissolution rate under a certain shape through this machine, so as to meet the requirements of the steel plant "fine material into the furnace".

Feeding chain conveyor

◇ Materials that can be used for crushing

▷ Waste car body (excluding engine, gearbox, tires, etc.);

▷ Tinplate cans (beverage cans)

▷ Home appliances, such as washing machines, ovens, dry refrigerators, etc.; (excluding motors, compressors, shafts, etc.)

▷ Bicycles and similar domestic waste

▷ Thin and light bales with density below 500kg/m3 and diagonal size below 450mm;

▷ Empty cans (wash to remove thinners, paint, etc.), and are non-closed containers;

▷ Other scrap steel with a large wall thickness of 5mm (not referring to items that are not suitable for crushing, but refers to steel scraps whose supply port is within 70%

Note: If the crushed pieces are compressed bales with a density not greater than 500kg/m³, the output will be less than the capacity specified in this line.

It is forbidden to put explosive, flammable and toxic liquids, gases and dust into the equipment.

Plates and profiles with a wall thickness of more than 5 mm will be deformed under the force of the hammer because they stay in the crusher for a long time, causing serious wear on the broken parts. Avoid feeding in bulk. The materials must be loaded in a loose and fully mixed state.

Roller feeder and host

◇ Materials not suitable for crushing (take PSX-600 horsepower type as an example)

▷ Dangerous objects: sealed containers, pipes, etc.; objects that may cause explosions, fires, etc.;

▷ Scrap cars, etc.: main bodies other than passenger cars; engines, converters, differential gears, tires; closed high-pressure gas cylinders (hydraulic cylinders, etc.); large materials that need to be cut off or objects with a weight of more than 150kg;

▷ Others: iron block 10kg or more; steel plate 5mm or more or 20kg or more; section steel and rail with thickness of 5mm or more; steel pipe with wall thickness of 5mm or more×φ250×500L; cables, steel wires, steel wires; hardened shafts and sleeve parts; motors , Transformers, compressors; ingots, blanks and similar solid materials; materials with a diagonal size of more than 2000mm.

▷ The scrap metal input must be free of explosive, flammable and toxic liquids, gases and dust.

The following materials cannot be put into the equipment:

• Dangerous and explosive materials

• Natural objects or combustion-supporting objects

• Toxic or corrosive substances

• Refrigerant

• Transformer oil

• Asbestos

• Ammunition

• Airtight cylinders, containers/fuel tanks or other airtight hollow bodies

• Battery

• Pyrotechnic air bag and belt tensioner

• Materials whose size or shape may hinder the rotor (ie, unbreakable materials with a diameter greater than 180 mm).

Main motor

◇ Uses and advantages of crushed materials:

The scrap steel processed by the scrap steel crushing and conveying production line is clean and superb scrap steel, with a natural bulk density of 1.0 to 1.5 t/m3, which is an ideal steelmaking charge. In steel smelting, it has the following advantages:

• High yield rate, that is, the ratio of molten steel produced to scrap steel increased;

• The chemical composition of each furnace steel is stable;

• Since non-ferrous metals and non-metallic substances have been sorted, the sulfur and phosphorus content in molten steel is reduced;

• When mixed with other scrap steel, the broken steel can fill the gaps and increase the density of the feed;

• During smelting, the number of feeds is reduced.

• During smelting, electrode damage is reduced,

• During smelting, the furnace is heated evenly,

• The life of the refractory lining in the furnace is extended.

• Air pollution and slag reduction.

• Reduced power consumption per ton of molten steel.

Magnetic separator

◇ Features

The main structural features of the crusher: the lining board and the hammer head adopt special wear-resistant materials to increase the service life; and the hammer head adopts a movable installation structure. Once an unbreakable object enters the crusher, it can be thrown and avoided. The non-crushable safety door specially designed for the crusher can be opened to remove it from the machine, thereby reducing the damage to the machine.

The core function of the hydraulic roller compactor: it is the feed pre-processing machine of the crusher, which can pre-compress thin shells and light metal components with larger dimensions and smoothly enter the scrap steel material at the feed inlet of the crusher, thereby expanding The scope of processing materials of the crusher. At the same time, it plays a vital role in improving the production efficiency of the crusher.

Discharge belt conveyor

Working principle and process

◇ Working principle

The scrap steel crushing production line uses the principle of hammer hitting. Driven by a high-speed, high-torque and high-voltage motor, the hammer on the rotor of the main machine takes turns to hit the object to be crushed into the cavity, which is formed between the liner and the hammer. Space, tear the material to be crushed into crushed materials that meet the specifications, and then under the action of magnetic equipment, high-purity crushed steel can be obtained.

Dust removal equipment

◇ Work process

The material is loaded on the scale conveyor by the hydraulic grabbing machine (or electromagnetic chuck) (note that the feeding material must be even), the material is lifted to the double-roller feeder through it, and the material is squeezed by the double-roller to enter the crusher in a suitable size . The crusher is equipped with a water spray port, and the sprayed water can avoid dust and reduce the temperature of the hammer. For large, thick and unbreakable scrap steel, it can be ejected through the discharge door of the crusher. The crushable materials fall into the vibrating conveyor from the grid hole after crushing, and then are sent to the discharge belt conveyor, and then to the magnetic separation system. In the magnetic separation system, the broken steel is sucked up and sent to the stacking conveyor, and other materials fall onto the non-magnetic material conveyor through the hopper at the lower part of the magnetic separation system. The stacking conveyor can move around a fixed axis, and the crushing production line can be stacked in a large fan-shaped area. A suspended magnetic separator is installed above the non-magnetic material conveyor for secondary magnetic separation, which can suck out the remaining magnetic ferrous metal on the non-magnetic material conveyor, reduce the amount of scrap steel missed by the electromagnetic drum of the magnetic separation system, and improve the Recovery rate. The material separated by the non-magnetic material conveyor can be transported to the sorting workshop for the sorting personnel to manually select on it, and the non-ferrous metals such as copper and aluminum caught in the non-magnetic material can be selected to improve the recycling efficiency.
